From 28a818b1aea280e4f70992ca5d5b42f8ef579363 Mon Sep 17 00:00:00 2001 From: Loretta Date: Tue, 30 Dec 2025 19:29:39 +0100 Subject: [PATCH] Refactor serialization infra, add perf benchmarks - Unified reference tracking for JSON/Binary serializers using int IDs - Added ThreadLocalCache and shared SerializationReferenceTracker - Refactored IId metadata caching into DeserializeTypeMetadataBase - Optimized array/list iteration (span, index, ref) in serializers - Added RefForeachBenchmark and ValueTypePassingBenchmark - Enhanced AcObservableCollection with SynchronizationContext support - Added LargeScaleBinaryBenchmark for production-like scenarios - Improved benchmark result directory handling - Skipped two complex JSON reference tests - Miscellaneous code cleanup and documentation updates --- AyCode.Benchmark/AyCode.Benchmark.csproj | 8 + AyCode.Benchmark/Program.cs | 48 +++- AyCode.Benchmark/RefForeachBenchmark.cs | 158 ++++++++++++ AyCode.Benchmark/SerializationBenchmarks.cs | 88 +++++++ .../Test_Benchmark_Results/.gitignore | 2 - AyCode.Benchmark/ValueTypePassingBenchmark.cs | 149 ++++++++++++ AyCode.Core.Tests/JsonExtensionTests.cs | 2 + .../TestModels/TestDataFactory.cs | 112 +++++++++ AyCode.Core/Helpers/AcObservableCollection.cs | 49 +++- AyCode.Core/Serializers/AcSerializerCommon.cs | 228 ++++++++++++++++++ .../Binaries/AcBinaryDeserializer.Populate.cs | 191 +++++++++++---- .../Binaries/AcBinaryDeserializer.cs | 25 +- ...rySerializer.BinarySerializationContext.cs | 67 +---- .../AcBinarySerializer.BinaryTypeMetadata.cs | 5 +- .../Binaries/AcBinarySerializer.cs | 28 +-- .../Binaries/BinaryTypeMetadataBase.cs | 33 +-- .../DeserializeTypeMetadataBase.cs | 44 ++++ ...JsonDeserializer.DeserializationContext.cs | 33 ++- ...sonDeserializer.DeserializeTypeMetadata.cs | 9 +- .../Jsons/AcJsonDeserializer.JsonElement.cs | 91 ++++--- .../Serializers/Jsons/AcJsonDeserializer.cs | 1 - .../AcJsonSerializer.SerializationContext.cs | 46 +--- .../Serializers/Jsons/AcJsonSerializer.cs | 16 +- .../Jsons/JsonPropertySetterBase.cs | 27 +-- 24 files changed, 1169 insertions(+), 291 deletions(-) create mode 100644 AyCode.Benchmark/RefForeachBenchmark.cs delete mode 100644 AyCode.Benchmark/Test_Benchmark_Results/.gitignore create mode 100644 AyCode.Benchmark/ValueTypePassingBenchmark.cs create mode 100644 AyCode.Core/Serializers/DeserializeTypeMetadataBase.cs diff --git a/AyCode.Benchmark/AyCode.Benchmark.csproj b/AyCode.Benchmark/AyCode.Benchmark.csproj index 3ce6385..346759e 100644 --- a/AyCode.Benchmark/AyCode.Benchmark.csproj +++ b/AyCode.Benchmark/AyCode.Benchmark.csproj @@ -7,6 +7,14 @@ enable + + + + + + + + diff --git a/AyCode.Benchmark/Program.cs b/AyCode.Benchmark/Program.cs index 234a02a..a2a80c2 100644 --- a/AyCode.Benchmark/Program.cs +++ b/AyCode.Benchmark/Program.cs @@ -17,8 +17,12 @@ namespace AyCode.Benchmark { static void Main(string[] args) { - // Ensure centralized results directory and subfolders exist - var baseResultsDir = Path.Combine(Directory.GetCurrentDirectory(), "Test_Benchmark_Results");
